A car crash just outside Terminal 5 at Los Angeles International Airport and an anonymous call reporting a man with a gun in Terminal 4 incited panic Friday evening and triggered a large police response.

“Apparently there was a very loud crash. People inside the terminal did not know what was happening. Some people panicked and they self-evacuated from the terminal,” reported KCAL9′s Derek Bell.

A woman driving on the airport’s arrivals loop at about 7:30 p.m. lost control of her SUV, hitting another woman who was walking on a sidewalk before slamming into a parking garage across the roadway from Terminal 5, Los Angeles police Sgt. Mark Guardado said.

WZZM 13 tweeted that the car accident sounded like shots fired.

Soon after the car crash, an anonymous caller reported a gunman at a gate in Terminal 4, Castles said.
